A simple calculator based on a recursive descent parser.
Build and then run in terminal. You will see this information:
a simple expression calculator by MaxXing
based on a recursive descent parser
input > _
Enter the mathematical expression ending with a question mark after the input > cursor. Like:
input > 1 + 1 ?
All of the spaces in your input will be ignored.
Then press enter:
input > 1 + 1 ?
result > 2.000000
input > _
The result is 2.
This calculator supports only the following operators：
- Brackets: (, )
- Mathematical operation: **, *, /, %, +, -
- Bit operation: <<, >>, &, ^, |
- Logical operation: <=, <, >=, >, ==, !=
